1 Optoelectronics GainMaker High Output Node 5-40/ MHz Description The GainMaker High Output Node is designed to serve as an integral part of today s network architectures, and combines the superior proven technologies of both the GainMaker RF Amplifier and Prisma Optical components. The GainMaker High Output Node is capable of higher output levels than the standard GainMaker Node. Featuring three RF output ports, it is the ideal platform for delivering video (digital and analog) as well as high-speed data services over advanced hybrid fiber/coax (HFC) networks. With its modular design of fiber receiver, reverse fiber transmitter and RF amplifier electronics, the GainMaker High Output Node station can provide a variety of functions required by advanced networks. The GainMaker High Output Node accommodates a second forward receiver with an RF switch to accommodate forward path optical redundancy. Reverse traffic can be combined and routed to FP, DFB, or CWDM reverse transmitters. The High Gain Dual (HGD) launch amplifier module provides two high-level outputs (with the ability to split one internally to feed a third port). Additionally, the node is available with an optional custom status monitoring transponder for use with Scientific-Atlanta s ROSA / TNCS status monitoring and control element manager. On-board temperature, automatic gain control (AGC) levels, RF switch position, power supply condition, as well as other features/parameters can be monitored through this transponder. Features Capable of higher output levels than standard GainMaker Nodes Forward redundancy with two 1310/1550 nm optical receivers (optional) Uses plug-in accessories common to all GainMaker products Cable to Linear EQ in amplifiers I/S EQ spot provides 14.5 db of Linear tilt Local test points and LED indicators on optical receivers, transmitters, and optical interface board simplify installation and maintenance AGC has thermal mode, eliminating disruptive RF output variation in the event of pilot loss QAM Pilot AGC now available in addition to existing analog AGCs Optional plug-in Status Monitoring Optional 3-state reverse switch (on/off/-6 db) allows each reverse input to be isolated for noise and ingress troubleshooting (status monitoring required) Fiber Management tray provides easy access to fiber connections and folds back to provide access to optical transmitter and receivers Reverse input pad and RF test point for each reverse input port on launch amplifier allow optimum reverse path design and alignment

Reference output tilt and internal tilt are both Linear tilt. 2. Forward Gain and Noise Figure measured with 0 db input EQ and 1 db input pad. 3. Forward internal tilt specified is primarily due to an on-board equalizer and a factory configured 7.5 db cable to linear interstage equalizer (ISEQ). 4. The forward reference output tilt specified is achieved via field installation of appropriate input EQ, in conjunction with the internal tilt of the launch amplifier and the tilt associated with the optical link (transmitter/receiver combination). 5. Station performance can be determined by combining optic performance and launch amplifier performance. Stated distortion performance is for launch amplifier section operated at reference output levels and tilt. Consult Cisco System Engineering for CIN calculations. 6. Reverse output reference level at the RF output of the launch amplifier. 7. Reverse Operational Gain, Noise Figure, and Return Loss are specified without reverse switch option.
